description
The
TISP61CAP3
is
a
programmable
overvoltage protector designed to protect SLIC
applications against lightning and transients
induced by ac power lines. Normally the V
GG
(Gate) terminal will be connected to the negative
supply rail of the SLIC
When a negative transient exceeds the negative
supply rail voltage of the SLIC it will cause the
thyristor to crowbar, shunting the surge to
ground. The high crowbar holding current
prevents dc latchup as the transient subsides.
Positive transients are clipped by diode action.

Terminals K1, K2 and A correspond to the alternative
line designators of T, R and G or A, B and C. The
negative protection voltage is controlled by the voltage,
V
GG,
applied to the G terminal.

NOTES: 1. Above 70擄C, derate linearly to zero at 150擄C case temperature
2. This value applies when the initial case temperature is at (or below) 70擄C. The surge may be repeated after the device has
returned to thermal equilibrium.
3. Most PTT鈥檚 quote an unloaded voltage waveform. In operation the TISP essentially shorts the generator output. The resulting
loaded current waveform is specified.
